Which of the following is the most important storage requirement of the HIS System?

Question

Options

• AHigh performance
• BHigh reliability
• CHigh deduplication and compression ratio
• DIntelligent O&M

• A
  82% (14)
• B
  12% (2)
• D
  6% (1)

Explanation

High performance is the most critical storage requirement for a Hospital Information System (HIS) because clinical environments demand near-instant access to large medical imaging files (CT scans, MRIs), patient records, and real-time monitoring data - delays can directly impact patient care and outcomes. The sheer volume of concurrent read/write operations from multiple departments (radiology, pharmacy, ICU) makes I/O throughput and low latency the defining storage challenge.

Why the distractors are wrong:

• B (High reliability) - Reliability is essential for all enterprise storage systems, not a distinguishing requirement specific to HIS. It's a baseline expectation, not the primary driver.
• C (High deduplication and compression) - Medical imaging formats like DICOM are already compressed and contain unique patient data, so deduplication ratios are poor; this feature offers limited benefit for HIS workloads.
• D (Intelligent O&M) - Operational management is an administrative feature, not a storage requirement specific to HIS clinical needs.

Memory tip: Think "ER speed" - in a hospital emergency, every second counts. HIS storage must act like an ER: fast response above all else. Performance = patient outcomes.
